I'm Not Real, Doris!
My Esteem's rooted w/stock ms910svd rom. If I update will it affect my rooting? Should I do a reset first? If not will I need to delete new t-mobile software or will I even be able to root to t-mobile after? I need solid recon Intel before I advance. Or this is the first power move to make me conform to big brother or spend big bucks again for a new phone that I did'nt want to buy yet until the cdme phones are obsolete and then get the best phone available then not get one for a short time thing. (I'm not nuts, just cheap & don't like big changes till I say so) or am I just over thinking too much.
The update tool will update it to the new software and you will lose root. The good thing is that ZVE is still rootable using the ZVC root method. It is recommended to take out you're external sd card before the update and do a factory reset after the update. There already exist 2 roms for ZVE.

and good luck!
